WEBSITE: http://www.teachertube.com Practical modern day uses of logarithms are explained. The Richter scale the PH acidity of a solution the decibel scale and star magnitudes are explained calculating the age of something with radioactive dating as well as the basis of what a common base 10 log is. This is intended to be a short introduction to the priniciples of logarithms preparing for more detailed lessons on using logarithms in more of an academic setting. • For the earthquake example I noticed a mistake. The shaking amplitude of a 5.0 earthquake has 10 times the amplitude of a 4.0 earthquake. Text and recording say twice. That was a mistake.
